<Anchor> As the number of
breakthrough infections increases, the need for additional vaccinations has increased. As a result of SBS coverage, it was decided that AstraZeneca did not make additional purchases. It is said that Pfizer and Moderna are mainly imported. Moderna has a relatively high rate of myocarditis complications in young men, so a new strategy is needed.
This is Cho Dong-chan, a medical reporter.
<Reporter> This
is a reference material for the National Assembly review of next year's COVID-19 vaccine-related budget.
The Korea Centers for Disease Control and Prevention replied that it was difficult to accept the opinion of the welfare committee to secure a budget for purchasing AstraZeneca to secure various vaccines.
The Korea Centers for Disease Control and Prevention (KCDC) considered Pfizer and Moderna additional purchases in consideration of public preference, and Janssen and Novavax left open the possibility of use.
AstraZeneca said that it may not extend the contract production contract with SK Bioscience unless Korea makes additional purchases, and SK Bioscience is in talks.
Among experts, there is an opinion that the diversity of vaccines and the need to secure a certain amount in case of an emergency, and the opinion that there will be no problem in supply and demand are opposed.
Moderna, the main booster vaccine next year, is controversial over heart complications in young men.
A study by the French Ministry of Health found that for every 100,000 vaccinated men aged 12 to 29, heart complications were 2.7 in Pfizer and 13.3 in Moderna, both rare, but five times higher in Moderna.
This is presumably because Moderna's inoculation dose is higher than that of Pfizer.
The amount of mRNA in a single dose is 100 micrograms for Moderna, more than three times that of Pfizer 30 micrograms.
[Ki-Jong Hong / Editor-in-Chief of the Korean Vaccine Society: Since the clinical process is relatively short, we know little about safe doses compared to effective doses.] In
Finland, Norway, Sweden, etc., Moderna vaccination for men under 30 years of age was banned, and Japan decided to give Pfizer the next dose for those who developed heart complications after vaccination with Moderna.
The Korea Centers for Disease Control and Prevention (KCDC) said that it is closely monitoring this area as there are 3-4 times more modern or heart complications in the second than in the first.
