Vaccination of the new coronavirus that has started all over the world since December last year.
Is it okay for everyone to get a vaccine?
How long will the effect last?
WHO has summarized the points of the online press conference held on the 7th with the chairman of the expert advisory board.
Overall situation of the world
(Q)
Vaccine approval and inoculation have begun all over the world.
What is the overall situation in the world regarding the vaccine for the new coronavirus?
Catherine O'Brien, Head of Vaccination at WHO
"The situation is changing day by day. There are many vaccines that show efficacy against this disease, and multiple vaccines have been approved in different countries. Vaccines are now predominant. Vaccinations have begun in developed countries, but will soon begin in low- and middle-income countries. There are already at least three types of vaccines evaluated by the highest screening regulators. Authorities will review data on safety and disease-preventing effects, as well as quality of production. The three vaccines are AstraZeneca, Moderna, and Physer vaccines, at least as they meet the criteria. It has been approved in one country. There are several other vaccines that have publicly announced their effectiveness, and we are seeing data on those vaccines. China's Shinofarm There is also a vaccine developed by the Gamalaya Institute in Russia. Most importantly, there are many vaccines that have undergone clinical trials, and I want to approve the vaccine for the general public. We will spend weeks and months looking at the data to see if it's enough. "
Effective for mutant strains
(Q)
Mutant strains are spreading all over the world.
Is the vaccine effective against mutant strains?
Catherine O'Brien
"These vaccines have been evaluated in development and trials for their effectiveness against multiple different mutants. The virus is constantly changing. It's natural for the virus. The question is whether the mutations in the virus affect the disease itself, treatment methods, or vaccines. Several mutant strains have been identified around the world that are of concern for the spread of the infection. We are currently testing whether it will affect the effectiveness of the vaccine, but I am very confident that we need to get the existing vaccine as soon as possible. Mutations are not believed to change the effectiveness of the vaccine. "
If you have a medical history
(Q)
Can people with a medical history be vaccinated?
Alejandro Clavioto, Chairman
"
Depending on the
situation. Certainly, anyone who has had a serious or allergic reaction to another vaccine should not take it. For those who are allergic to food or other things, It is not necessary to avoid it, but we recommend that vaccination should be done in a place where it can be effectively and immediately treated if the recipient has severe allergic symptoms. "
Catherine O'Brien
" With underlying illness People with heart and lung disease, people with diabetes and obesity have been found to be at higher risk than others when infected with the new corona virus. Those who do have people who want to get the vaccine. There is no data on how it affects pregnant women, but I would like to emphasize that these vaccines may be harmful to pregnant women and the fetus. There is no reason to believe that it is not. Talk with pregnant women who belong to the high-risk groups listed above, especially those who are vaccinated, especially for healthcare professionals. If you decide that you are at high risk, you can vaccinate. People with HIV should be vaccinated, and who is at high risk of becoming severely ill by being infected with the new corona virus. Should be vaccinated. "
Should people who have recovered be inoculated?
(Q)
Should people who have already recovered from infection with the new coronavirus be vaccinated?
Chair Alejandro Clavioto
"That
's what
we especially recommend. People who test positive for PCR or antigens should not be excluded from vaccination. How long a person once infected will not be infected again. I don't know yet. The data released yesterday (6th) stated that it would not be infected for up to 8 months, but it should not be excluded from vaccination. On the other hand, once infected, the person himself first If older people think they should be given priority and wait for them to get vaccinated, it's up to them to decide, "
Catherine O'Brien,
" Alejandro says. Vaccination is the world. It's just getting started, and countries are starting with the people who should be given the highest priority. Those who have already been infected are very unlikely to get infected again for at least the next 6 months, but WHO. We do not recommend excluding people who have been infected once or delaying them because they have been infected. "
What is the difference between the first and second vaccines?
(Q)
Can the vaccine to be inoculated be the first and second vaccines made by different manufacturers?
Catherine O'Brien
"In some countries, more than one vaccine has already begun to be used. There is no data on whether it is okay to give a second vaccine that is different from the first. At this stage, we recommend that if you get the first vaccine, such as Physer, you should get the same vaccine the second time. In some countries, the second dose is different from the first. I know I'm using vaccines. This is a very important area to study and I will prioritize my research to make recommendations. "
The effect of the vaccine
(Q)
How long will the vaccine be effective?
Catherine O'Brien
"The clinical trials just started last spring and it's still young, so if you keep looking at the people who participated in the clinical trials, you'll see how effective they are. I don't know yet. I wish I could get a lasting immunity. I'm also looking at how long the immunity of people infected with the new corona virus will last, maybe vaccinated. It may also be related to the duration of immunity obtained. At this stage, it is too early to explain how long the vaccine will last. "
Children under the age of 15
(Q)
Regarding vaccines such as Pfizer, it is said that you can be vaccinated over 16 years old. What should I do for children and babies under 15 years old?
Catherine O'Brien
"Studies are still going on. Clinical trials have ruled out people under the age of 16, but now more research is being done to see how it works for children between the ages of 12 and 16. So, in the future, information should come out. The advisory board recommends that people under the age of 16 not be vaccinated due to lack of data, but WHO Depending on the situation, vaccinated workers may be at risk of developing a very serious medical condition by consulting with their family about a child with a disease and being infected with the new corona virus. You may choose to get vaccinated, but we do not recommend it. I am not saying yes in any environment. "
