It was given emergency use authorization by the World Health Organization in December.\nNo significant vaccine failure\nPfizer and BioNTech pointed to data fromIsrael’s health ministry that said there was decreased effectiveness in their vaccine,in terms of preventing infection and symptomatic disease.\nThe decline in efficacy coincided with the spread of the delta variant and the end of most Covid measures in Israel. The shot remains 93% effective in preventing hospitalizations and serious illness from Covid-19, the ministry reportedly said.\n\n The vaccine failures are really low at this time for the current vaccines that have been deployed. So until that shifts, I don’t think it would be prudent to deploy a booster dose.Norman BaylorBIOLOGICS CONSULTING CEO\n\nBut Baylor, who is currently president and chief executive officer of Biologics Consulting, said close monitoring has not revealed “significant vaccine failures” so far.\n“We’re just not seeing that now,” he told“Street Signs Asia”on Thursday.\nCovid cases are rising in the U.S. again, butdoctors say the increase in cases and hospitalizations are due to the delta variant spreading in unvaccinated populations.\n“The vaccine failures are really low at this time for the current vaccines that have been deployed. So until that shifts, I don’t think it would be prudent to deploy a booster dose,” Baylor said.\nHe said health agencies seem to be in agreement that a third dose is not needed.\n“We’re just not there yet … we don’t have the evidence that it’s time for a booster,” he said, adding that in future, there could be new variants that render current vaccines ineffective or much less effective.\nVaccine inequality\nRicher countries have been able to vaccinate large numbers of their population, while poorer countries lag behind.\nThe issue of vaccine disparity between regions needs to be addressed, Baylor said.\n“A pandemic itself, the definition is that it’s global,” he said, adding that he agrees with the World Health Organization that the crisis needs to be looked at from a global perspective.\n\n Some countries and regions are actually ordering millions of booster doses before other countries have had supplies to vaccinate their health workers and most vulnerable.Tedros Adhanom GhebreyesusDIRECTOR-GENERAL, WORLD HEALTH ORGANIZATION\n\nWHO Director-General Tedros Adhanom Ghebreyesus said Monday thatthe world is “in the midst of a growing two-track pandemic.”\n“Some countries and regions are actually ordering millions of booster doses before other countries have had supplies to vaccinate their health workers and most vulnerable,”he said during a press briefing, adding that the world ismaking “conscious choices” not to protect those who are most in need.\nData suggests the vaccines offer long-lasting immunity against severe and deadly Covid-19, he said.\n“The priority now must be to vaccinate those who have received no doses and protection,” the WHO chief said.\nBiotech companies like Pfizer-BioNTech andModerna, which developed another mRNA vaccine for Covid-19, need to “go all out” to channel supplies to places in need, including through the Covax vaccine distribution alliance, he added.","news_type":1},"isVote":1,"tweetType":1,"viewCount":389,"commentLimit":10,"likeStatus":false,"favoriteStatus":false,"reportStatus":false,"symbols":[],"verified":2,"subType":0,"readableState":1,"langContent":"EN","currentLanguage":"EN","warmUpFlag":false,"orderFlag":false,"shareable":true,"causeOfNotShareable":"","featuresForAnalytics":[],"commentAndTweetFlag":false,"andRepostAutoSelectedFlag":false,"upFlag":false,"length":5,"xxTargetLangEnum":"ORIG"},"commentList":[],"hasMoreComment":false,"orderType":2}
