Specialist in virology reveals the results of the study. Injection of vaccination needle 1 – needle 2 alternate types. Found immunity that occurs. get a very high quantity It is expected to be clear by the end of this month.
On 7 July 64, Prof. Dr. Yong Phuworawan, head of the Center specializing in virology Clinic, Department of Pediatrics Faculty of Medicine Chulalongkorn University Facebook post Yong Poovorawan states that the COVID-19 vaccine, injection 1 and needle 2 are interchangeable.
Currently also recommended Vaccination against covid 19, needle 1 and needle 2 are the same type.
Currently, there is a trend, there is information and is studying different types of vaccines in the 1st and 2nd doses.
For example, the virus vector (AstraZeneca) is alternated with mRNA (Pfizer) and it is becoming more accepted.
In Thailand we currently have a lethal vaccine (Sinovac. sinopharm) against virus vector (AstraZeneca) and in real life. In some people who are allergic to the first dose vaccine, the second dose vaccine is different. There are quite a number of them now. I understand that there are more than 1000
center education A study of alternating vaccine types was conducted. under study
It was found that the first dose was inactivated vaccine (Sinovac) and 3-4 weeks later the virus vector vaccine (AstraZeneca). get a very high quantity Approximately 8 times higher than the 2 doses of Sinovac vaccine 3-4 weeks apart, or approximately 10 times higher than the actual immunity in patients, and less than the 2 doses of the virus vector AstraZeneca vaccine. 10 weeks apart, just a little.
alternate vaccination The second dose is a vector virus (3-4 weeks apart), which gives people who have been vaccinated with high immunity in just 6-8 weeks, as opposed to those who have received two vector vaccine doses. (10 weeks apart) to achieve such high immunity, it takes at least 12-14 weeks.
Such information is therefore useful. During the epidemic and make those who are vaccinated with higher immunity And at the same time administering vaccines will be easier. In the event that there is a vaccine in limited quantities All studies should be clearer by the end of the month.
However, the data obtained is still the study of the level of immunity. What is important to continue studying is the ability to prevent disease Although it is known that higher levels of immunity have a greater chance of preventing disease and its severity. A broader study is also needed to determine the efficacy of vaccines in preventing disease if they are given alternately.
