It is unknown at this time what he will do after leaving the post. The World Health Organization (WHO) on Thursday called on the world’s richest nations not to stockpile vaccines.
Kate O’Brien, a World Health Organization (WHO) vaccine consultant, warns that rushing to stockpile vaccines until there is adequate evidence of the need for additional doses of vaccines could exacerbate existing vaccine disparities around the world.
New World Health Organization concerns about vaccines
O’Brien added that regardless of the situation, rich countries are once again on the path to surplus vaccines.
Earlier on Wednesday, Pfizer and Bioentech released preliminary test results, saying that their ticker booster dose provides effective protection against the ammonia type of corona. At the end of a short-term study, the two organizations reported that the same amount of protection that two doses of tick came with against other types of corona would require the same amount of protection to get the same protection.
Pfizer chief executive Albert Borla issued a statement on the booster dose. There, he said, an extra dose of ticker would increase protection against antimicrobials. There is also a booster dose as the best way.
The World Health Organization says it is examining Pfizer and Bioentech data. O’Brien said that while the extra dose is beneficial in providing additional protection against amoxicillin, it is still in its infancy.
Meanwhile, an expert panel of the World Health Organization said that it is better to give two doses of the same vaccine to protect against corona. However, in countries where there is a shortage of vaccines, a mixed dose is a good solution. “We still think the best way is to use the same vaccine for two initial doses,” said Alejandro Cravieto, chairman of the expert panel, at a news briefing yesterday.
Earlier this week, a study from Oxford University found that mixing doses of AstraZeneca or Pfizer vaccines with other vaccines had the lowest risk.
