[국제]The effectiveness of a single vaccination is reported, but “keep careful”… why?

[앵커]

The controversial COVID-19 vaccine has been reported one after another by expanding the vaccination interval.

Although there are reports that the first vaccination alone is effective in prevention, it is pointed out that the details should not be relieved.

I found out why.

After each pharmaceutical company announced the results of phase 3 clinical trials for its Corona 19 vaccine last year, a specific research team is releasing the results of follow-up studies on these vaccines.

The focus of all research is on how effective the vaccine is after the first dose.

Looking at the contents, although the methods of producing antibodies were different, the time when the effects were high was similar.

Pfizer vaccine starts on day 21 and AstraZeneca vaccine starts on day 22.

The prevention effect at this time is 90% Pfizer and 76% AstraZeneca.

Only AstraZeneca was reported for the duration of the effect, up to 12 weeks.

According to the results, both Pfizer and AstraZeneca vaccines are the first dose to have some preventive effect.

It is considerably higher compared to the final clinical trial released by the pharmaceutical company after the second vaccination was completed.

However, it is pointed out that it is necessary to be cautious in continuing the policy to extend the actual vaccination period.

Israeli health authorities, whose primary vaccination and quarantine effects of Pfizer’s vaccine have been highly investigated, are also on the lookout for premature vigilance.

In addition, the fact that the immunity effect of the first vaccination was high is that it may be poisonous in terms of quarantine if only the numbers are transmitted.

Therefore, experts point out that in Korea, where vaccination to the public is imminent, detailed vaccination guidelines, such as whether or not the vaccination interval should be expanded, and the details of personal quarantine after vaccination, should be completed.

In addition, even if the guidelines are announced, it is emphasized that it is necessary to make timely corrections and supplements according to the changing circumstances and to communicate transparently with the public.
