The COVID-19 vaccine provides hope for getting rid of the pandemic. They also raised many questions. Here are some answers.
Are they safe? What are the side effects?
After an in-depth review by the US Food and Drug Administration (FDA), it was found that the two vaccines authorized by Pfizer and Moderna in the United States are safe.
Experts reviewed the safety data of approximately 30,000 people who participated in clinical trials of each vaccine, and millions of people have now received the vaccine. Severe side effects are extremely rare, and so far include severe allergic reactions in a small number of people. According to data from the Centers for Disease Control and Prevention (CDC), the incidence of severe allergic reactions is approximately 4.5 injections per 1
The Centers for Disease Control and Prevention stated: “If this happens, vaccinators can use drugs that are effective and immediately treat the reaction.”
Mild reactions that disappear after a few days are more common. These include pain, fatigue, headache, and chills at the injection site. CDC even has a smartphone app to help track reactions.
How are their working conditions?
It has been found that both Pfizer and Moderna vaccines can work well, which is beyond the previous guesses of many experts. Both vaccines are approximately 95% effective in preventing people from getting COVID-19 in clinical trials.
Does it cost money to buy a vaccine?
Do not. Even if you do not have health insurance, it is free.
Which vaccine should I get? Is one better than the others?
Both Pfizer and Moderna vaccines work very well, and experts say that people should get either vaccine from a specific location.
If the vaccine is additionally authorized, the choice may become more complicated. For example, Johnson & Johnson has filed an application with the FDA and may get approval later this month or early March.
The overall effective rate of the vaccine is 66%. Although it is low, it is still higher than the minimum 50% set by the FDA.
Ashish Jha, Dean of the Brown University School of Public Health, still wrote in the Washington Post that Johnson & Johnson is 100% effective in what really matters: preventing hospitalization and death.
He wrote: “If you can get a vaccine-any vaccine-you can get it.”
How long can I be protected after vaccination? How long does it last?
The CDC said the second dose may take up to two weeks to get full protection. Both Pfizer and Moderna vaccines require two doses. Nevertheless, some protection can be established even after the first dose.
It is not clear how long the protection will last. In the next few years, more shooting may be needed. Researchers need more time to continue to pay attention to study participants to see if the vaccine protection will continue or disappear over time.
Do I still need to wear a mask and take preventive measures after vaccination?
CDC recommends that you do the same. why? Because although vaccines are very effective in preventing diseases, there is less evidence about whether you can still transmit the virus to other people, which means that wearing a mask and keeping your distance from others is still important until more people get the vaccine.
The good news is that there is early evidence that the vaccine does reduce the spread of the virus to other people.

In addition, the Centers for Disease Control and Prevention (CDC) stated that if you are fully vaccinated, you do not need to be isolated if you are exposed to the virus.
When can I get the vaccine? Where am i going?
The eligibility of the vaccine is determined by each state, although the federal government has recommendations.
Vaccination mainly starts with medical staff and people in nursing homes. Now, they have developed into categories such as those over 65 and basic workers in many places. Ordinary people who are not in these categories are not yet eligible.
It is not clear when everyone will be eligible, but it is expected to be sometime in the spring. Even so, once everyone opens the door, everyone can actually make an appointment and get the opportunity.
How to register also depends on your status and location. There are multiple ways, including pharmacies such as CVS, other health care providers, and large-scale vaccination sites such as stadiums.

How does the vaccine work?
Both Pfizer and Moderna vaccines are a new technology mRNA vaccine. The mRNA vaccine provides the human body with a part of the genetic code of the coronavirus, which is called the spike protein, which is used to enter cells. Then, the body triggers an immune response to these spike proteins and teaches them how to fight the virus.
The vaccine cannot bring you the coronavirus, because the vaccine does not contain the virus and will not change your DNA in any way.
Did you catch the vaccine?
Given that this process usually takes several years, the time to develop a vaccine is very short. But the speed is not due to cutting corners. Both Pfizer and Moderna vaccines have undergone three phases of clinical trials, with approximately 30,000 people in the third phase of the trial, and passed the public hearings of the expert advisory group to conduct a complete FDA review process. The urgency of the crisis has accelerated, which means that sufficient funds are available, including funds from the government, and because the two companies started manufacturing doses even before the trials were completed.
Can the vaccine still resist new variants of the virus?
New, more infectious variants of the virus have attracted attention and caused a surge in cases in certain countries. The good news is that the current vaccines have proven to work well for the most common variant, which was first discovered in the UK.
Experts are more worried about a variant first discovered in South Africa. Studies have shown that this variant can reduce the level of antiviral antibodies produced by the vaccine, although it is not clear how much effectiveness can be reduced for Pfizer and Moderna vaccines.
Moderna said in late January that despite the decline in antibody levels, it is still “expected to exceed protective levels.”
Fauci said on MSNBC that these vaccines can still provide protection, especially in the most important aspect: preventing serious diseases that can be hospitalized or kill you.
He said: “The effectiveness of the vaccine is sufficiently buffered, so it still has a certain protective effect, especially for serious diseases.”
It is not clear whether Pfizer and Moderna vaccines need to be updated for new variants, but the two companies are investigating this possibility.
What happens if I miss the second dose?
Pfizer vaccine plans to have a second vaccination 21 days after the first vaccination, and Moderna vaccine for a second vaccination 28 days later. However, if you miss this day, don’t panic. You should still take the medicine again, but the CDC says that although it is best to take the medicine on time, if you miss the window, you can take it within 6 weeks after the first dose.
Can children be vaccinated?
not yet. Pfizer and Moderna vaccines are currently only available for 16 years and older and 18 years and older respectively. Children need other research. According to Fauci, data on children aged 12 to 17 are expected to be released sometime in the fall, but data on children younger than 12 will not be available until the first quarter of next year.
Should I get the vaccine if I have an allergic reaction?
Yes it is. The FDA recommends that people avoid using the vaccine only if they are allergic to vaccine ingredients. (The ingredients are listed here and here.)
Should I be vaccinated if I am pregnant?
The CDC says pregnant women can be vaccinated, although they may want to discuss the issue with their doctor. “Experts think [the vaccines] The CDC pointed out that this is unlikely to pose specific risks to pregnant people. “However, the actual risks of mRNA vaccines for pregnant women and fetuses are unclear, as these vaccines have not been studied in pregnant women.”
If I already have COVID-19, should I get the vaccine?
CDC says you should. That’s because it is not clear how long the immunity of this virus can last. Some studies have shown that people who have been vaccinated with the virus may only need one dose of the vaccine, because the vaccine helps to increase the level of protection already available.
