How long is the validity period of COVID-19 vaccine? Description of the expiry date of COVID-19 vaccine

How long is the vaccine valid in COVID-19? Vaccination in COVID-19 has started in an orderly manner. Everyone has joined the vaccination team, but even the best vaccine is effective. So how long is the validity period of COVID-19 vaccine? Let's have a look.

The protection rate of different vaccines is basically the same. Disease control experts say that any vaccine will eventually fade. Generally speaking, it will obviously fade after more than 6 months. COVID-19 vaccine has a similar phenomenon, so it is not only valid for 6 months, but also valid for 6 months. Six months later, it is still more immune than residents who have not been vaccinated with COVID-19 vaccine.

One shot is a vaccine whose immunity is generally weaker than two shots and three shots, and it is sensitive to virus mutation. It is suitable for people who have temporary or urgent tasks and need to go to epidemic areas for vaccination.

The production of double vaccine is simple, rapid and safe, but its disadvantages are large dosage, short immune cycle and single immune route, which is suitable for most people.

The production of three needles does not need complete virus, which is safe and reliable, easy for mass production and low in cost; But the disadvantage is that it needs three injections, and the inoculation period is long, which is suitable for people who live in low-risk areas and have enough time to inoculate;

This is the expiry date of COVID-19 vaccine. I hope it helps you.
