Corona news.

Starting tomorrow (14th), the 4th dose of the Corona vaccine for those over 60 will start.

As time passes, the effectiveness of the vaccine is diminishing, and most of the severe cases and deaths are from the elderly, but for more information, medical reporter Yoo Seung-hyun reports.


The target for the fourth vaccination, starting tomorrow, is 60 years old or older who were born before 1962.

120 days must pass after the third dose.

The government explained the reason for the expansion of the fourth vaccination as follows.

[Jeong Eun-kyung/Director of the Korea Centers for Disease Control and Prevention: The effectiveness of the vaccine is decreasing as more than 4 months have passed since the third dose, and 85% of severe cases and 95% of deaths occur in those over 60.

] Vaccination was strongly recommended for those over the age of 80, who accounted for 64% of deaths.

Those eligible for vaccination can reserve the remaining vaccine on Naver or Kakao from tomorrow, or apply for a preliminary list at a medical institution by phone to receive inoculation.

Online advance reservations will start from the 18th, and reservations will be made from the 25th.

If you want to get Pfizer or Moderna vaccines, you can also get Novavax vaccines.

After 4 weeks of the 4th vaccination, the effect of preventing infection was twice as high as that of the 3rd vaccination, and the effect of preventing severe diseases was 3.5 times higher.

In particular, the severe preventive effect did not decline even after at least 6 weeks.

Adverse reactions stopped at muscle pain, headache, and fever, and disappeared within an average of 1.7 days.

In the US, UK, France, and Israel, the 4th dose is also being given to the elderly, but the recommended age and interval are slightly different.

The quarantine authorities have not yet planned to expand the fourth dose to the general public under the age of 60, but said they will periodically review domestic and international circumstances.
