From the moment the coronavirus was declared a pandemic by the World Health Organization (WHO), the race to find a vaccine for COVID-19 followed. Numerous vaccine trials have taken place, but no vaccine has shown any promise.
“Today is a great day for science and humanity. The first set of results from our Phase 3 COVID-19 vaccine trial provide initial evidence of our vaccine's ability to prevent COVID-19, ”said Dr. Albert Bourla, CEO of Pfizer.
The vaccine has given many confidence that the pandemic will end, as BioNTech CEO Ugur Sahin hopes life will return to normal by next winter.
“This vaccine is a huge step forward, not only for the pandemic but also for scientists and vaccine makers. We have never created a vaccine for a global pandemic so quickly in the hope that it will be so effective. This vaccine could lead to a dramatic reduction in the spread, ”said Nicholas Voong, a junior at Carlmont.
Despite positive test results, the vaccine is awaiting regulatory approval. According to CNNAmericans should not expect any clearance from the US Food and Drug Administration (FDA) until the last half of December.
Given the uncertainty of the vaccine, the Centers for Disease Control (CDC) produced a vaccination plan "provisional playbookThat Alex Azar, US Secretary of Health and Human Services, intends to follow. As part of the plan, essential workers and those at higher risk will be the first to receive the vaccine, although the plan is not fully finalized.
Aside from who gets the vaccine first, the federal government estimates that the sooner the general public will receive the vaccine is likely to be in the spring of 2021.
“I think it's fair that medical workers and frontline workers get the vaccine first because they're the most likely to get COVID-19. Although spring is a few months away, it is good that we have a vaccine that is likely to be as effective, ”said junior Nadine Lahlouh.
Pfizer has shed light on the future distribution of its COVID-19 vaccine because it presents a potential hurdle: It must be stored at around 70 degrees Celsius (94 degrees Fahrenheit).
This cold temperature is rare for a vaccine. According to NPRThis presents a challenge for some distributors who are struggling to find dry ice or other mechanisms to keep the vaccine cold, because a negative temperature of 70 degrees Fahrenheit is cooler than a refrigerator.
“We have developed packaging and storage innovations tailored to the range of locations where we expect vaccinations will take place. We have already launched the development of innovative cold chain and distribution logistics solutions to facilitate vaccine supply, ”said Steven Danehy, spokesperson for Pfizer.
Given the distribution plans, the next step for the vaccine is the determination of side effects; according to NBC News, scientists predict that the injections will cause annoying flu-like side effects, such as arm pain, muscle aches, or fever that could last for a few days.
“The biggest tragedy would be if we had a safe and effective vaccine that people are reluctant to get,” said Dr. Preeti Malani, chief medical officer and professor of medicine at the University of Michigan at Ann Arbor, in an interview. with NBC News.
November 16, Moderna, a U.S. biotech company, said its vaccine is 94.5 percent effective against COVID-19, according to early data.
“We are now receiving two vaccines with surprisingly high efficacy rates. It is extremely exciting to watch. The next step is to test them over the next two weeks to determine their potential side effects, ”said Teasha Zhou, junior at Carlmont.
The company says its vaccine has had no known serious side effects, and according to CNN, a small percentage of those who received it experienced symptoms such as body aches and headaches.
While the two vaccines are similar in their mechanisms, using mRNA to fight the coronavirus, the Moderna vaccine has some advantages over the Pfizer-BioNtech vaccine.
Moderna vaccine can be stored at a negative temperature of 20 degrees Celsius (less than 4 degrees Fahrenheit) compared to the Pfizer-BioNtech vaccine which must be stored at a negative temperature of 70 degrees Celsius. Due to its lower storage temperature, the Moderna vaccine can be stored in freezers which are already available in many hospitals and pharmacies, while the Pfizer-BioNtech vaccine requires dry ice or a colder freezer for storage. .
In addition, the Moderna vaccine can be stored for 30 days in the refrigerator, while the Pfizer-BioNtech vaccine can only last for five days in the refrigerator at a negative temperature of 70 degrees Celsius.
“It's a vaccine race. The only thing you need to do is test for side effects, get it approved, and then start shipping it to everyone. We are very close to the end of this pandemic, ”Zhou said.
If you’re having dysfonctionnement beginning an exercise plan or following through, you’re not alone. Many of us struggle getting out of the sedentary rut, despite our best intentions.
You already know there are many great reasons to exercise—from improving energy, mood, sleep, and health to reducing anxiety, stress, and depression. And detailed exercise instructions and workout orgie are just a click away. But if knowing how and why to exercise was enough, we’d all be in shape. Making exercise a habit takes more—you need the right mindset and a smart approach.
While practical concerns like a busy schedule or poor health can make exercise more challenging, for most of us, the biggest barriers are esprit. Maybe it’s a lack of self-confidence that keeps you from taking positive steps, or your détermination quickly flames out, or you get easily discouraged and give up. We’ve all been there at some point.
Whatever your age or sport level—even if you’ve never exercised a day in your life —there are steps you can take to make exercise less intimidating and painful and more fun and instinctive.
Ditch the all-or-nothing attitude. You don’t have to spend hours in a gym or force yourself into monotonous or painful activities you hate to experience the physical and emotional benefits of exercise. A little exercise is better than nothing. In fact, adding just modest amounts of physical activity to your weekly routine can have a profound effect on your mental and emotional health.
Be kind to yourself. Research shows that self-compassion increases the likelihood that you’ll succeed in any given endeavor. So, don’t beat yourself up about your body, your current fitness level, or your supposed lack of willpower. All that will do is demotivate you. Instead, look at your past mistakes and unhealthy choices as opportunities to learn and grow.
Check your expectations. You didn’t get out of shape overnight, and you’re not going to instantly transform your body either. Expecting too much, too soon only leads to frustration. Try not to be discouraged by what you can’t accomplish or how far you have to go to reach your fitness goals. Instead of obsessing over results, focus on consistency. While the improvements in mood and energy levels may happen quickly, the physical payoff will come in time.
Many of us feel the same. If sweating in a gym or pounding a treadmill isn’t your idea of a great time, try to find an activity that you do enjoy—such as dancing—or pair physical activity with something more enjoyable. Take a walk at lunchtime through a scenic park, for example, walk laps of an air-conditioned mall while window shopping, walk, run, or bike with a friend, or listen to your favorite music while you move.
Even the busiest of us can find free time in our day for activities that are important. It’s your decision to make exercise a priority. And don’t think you need a full hour for a good workout. Short 5-, 10-, or 15-minute bursts of activity can prove very effective—so, too, can squeezing all your exercise into a couple of sessions over the weekend. If you’re too busy during the week, get up and get moving during the weekend when you have more time.
The key thing to remember about starting an exercise program is that something is always better than nothing. Going for a quick walk is better than sitting on the couch; one minute of activity will help you lose more weight than no activity at all. That said, the current recommendations for most adults is to reach at least 150 minutes of moderate activity per week. You’ll get there by exercising for 30 minutes, 5 times a week. Can’t find 30 minutes in your busy schedule ? It’s okay to break things up. Two 15-minute workouts or three 10-minute workouts can be just as effective.
For most people, aiming for moderate intensity exercise is sufficient to improve your overall health. You should breathe a little heavier than normal, but not be out of breath. Your body should feel warmer as you move, but not overheated or sweating profusely. While everyone is different, don’t assume that training for a marathon is better than training for a 5K or 10K. There’s no need to overdo it.
Health issues ? Get medical clearance first. If you have health concerns such as limited mobility, heart disease, asthma, diabetes, or high blood pressure, talk with your doctor before you start to exercise.
Warm up. Warm up with dynamic stretches—active movements that warm and flex the muscles you’ll be using, such as leg kicks, walking lunges, or arm swings—and by doing a slower, easier version of the upcoming exercise. For example, if you’re going to run, warm up by walking. Or if you’re lifting weights, begin with a few light reps.
Drink plenty of water. Your body performs best when it’s properly hydrated. Failing to drink enough water when you are exerting yourself over a prolonged period of time, especially in hot conditions, can be dangerous.
There’s a reason so many New Year’s resolutions to get in shape crash and burn before February rolls around. And it’s not that you simply don’t have what it takes. Science shows us that there’s a right way to build vêtements that last. Follow these steps to make exercise one of them.
A goal of exercising for 30 minutes a day, 5 times a week may sound good. But how likely are you to follow through ? The more ambitious your goal, the more likely you are to fail, feel bad about it, and give up. It’s better to start with easy exercise goals you know you can achieve. As you meet them, you’ll build self-confidence and momentum. Then you can move on to more challenging goals.
Triggers are one of the confidentiels to success when it comes to forming an exercise habit. In fact, research shows that the most consistent exercisers rely on them. Triggers are simply reminders—a time of day, place, or cue—that kick off an automatic reaction. They put your routine on autopilot, so there’s nothing to think about or decide on. The alarm clock goes off and you’re out the door for your walk. You leave work for the day and head straight to the gym. You spot your sneakers addict right by the bed and you’re up and running. Find ways to build them into your day to make exercise a no-brainer.
People who exercise regularly tend to do so because of the rewards it brings to their lives, such as more energy, better sleep, and a greater sense of well-being. However, these tend to be long-term rewards. When you’re starting an exercise program, it’s important to give yourself immediate rewards when you successfully complete a workout or reach a new fitness goal. Choose something you look forward to, but don’t allow yourself to do until after exercise. It can be something as simple as having a hot bath or a favorite cup of coffee.
If your workout is unpleasant or makes you feel clumsy or inept, you’re unlikely to stick with it. Don’t choose activities like course or lifting weights at the gym just because you think that’s what you should do. Instead, pick activities that fit your lifestyle, abilities, and taste.
Activity-based video games such as those from Wii and Kinect can be a fun way to start moving. So-called “exergames” that are played standing up and moving around—simulating dancing, skateboarding, soccer, bowling, or la petite balle jaune, for example—can burn at least as many kcal as walking on a treadmill; some substantially more. Once you build up your confidence, try getting away from the TV screen and playing the real thing outside. Or use a smartphone app to keep your workouts fun and interesting—some immerse you in interactive stories to keep you motivated, such as running from hordes of zombies !
