[Q&A] One bottle of Pfizer → 7 people inoculated? What is the lasting effect of the vaccine?

If you

have any other questions about the

vaccine, I would like to ask a medical reporter Cho Dong-chan.

[Dong-chan Jo/medical journalist (specialist): Let's look at the foreign press first.

The news was reported on the 2nd of last month that a Finnish nurse gave a bottle of Pfizer vaccine to 7 people.

Is there a technology that can only hit 7 people in Korea?

Also, is it not just Korea squeezing to hit one more person?

The U.S. government banned 7 people per bottle of Pfizer vaccine on January 15th, and the reason was surprising.

You can hit 7 people per bottle at first using a special syringe, but is this still possible?

I signed a contract for 6 people per bottle, but if you continue to inoculate 7 people at a time, it will be a loss for the pharmaceutical company.

So the dose per bottle can be reduced to only fit 6 people.

If that happens, the 2nd vaccination schedule may be tweaked, so we're just going to inoculate 6 people per bottle.

However, it should be seen that the US government banned it, but it was mentioned that the safety and effectiveness of 7 vaccinations are the same. It seems that we need to be calm and judge according to our circumstances.]

[Cho Dong-chan/medical reporter (specialist): Antibodies are produced a week after receiving the vaccine, but the amount of antibodies decreases rapidly from about 3 months.

So, after three months of vaccination, you can get reinfected, and if it's a mutant virus, you can get infected earlier than that.

This is why you should keep wearing a mask even if you get the vaccine.

[Cho Dong-chan/medical reporter (specialist): That's not true, but the antibody that prevents the virus from entering decreases after three months, but the immune cells that fight the virus that enter the body are six months, one year.

There are even predictions that it will remain effective for 2-3 years.

It may not take at all during the period when the immune cells are activated, but it takes less and the symptoms are mild.

However, since the duration may vary from vaccine to vaccine, it is important to have sufficient strategies to secure various vaccines.]
