Africa-Press<\/a> – Namibia<\/a>. <\/strong><\/span>Covid-19 vaccines work so well that most people don\u2019t yet need a booster, an all-star panel of scientists from around the world said in a review that\u2019s likely to fuel debate over whether to use them.<\/p>\n

Governments would be better served to focus on immunizing the unvaccinated and to wait for more data on which boosters would be most effective and at what doses, the authors, who included two prominent U.S. Food and Drug Administration experts, argued in the medical journal The Lancet.<\/p>\n

They based their assessment on a wide range of real-world observational studies as well as data from clinical trials. \u201cNone of the studies has provided credible evidence of substantially declining protection against severe disease,\u201d the authors wrote. There could also be additional side-effect risks if boosters are introduced too soon or too broadly, they said.<\/p>\n

Most countries with ample vaccine supplies are debating whether to allocate doses for booster shots to prop up immunity and potentially help stop the spread of the more infectious delta variant.<\/p>\n

The U.S. plans to roll out booster shots starting Sept. 20, though the proposal still needs sign-off from the FDA and the Centers for Disease Control and Prevention.<\/p>\n

Scientists are by no means unanimous on the topic of boosters. Even a small reduction in efficacy against the spread of Covid can strain a health-care system, and \u201cthere is therefore no \u2018one size fits all\u2019 approach,\u201d said Azra Ghani, chair in infectious disease epidemiology at Imperial College London, who wasn\u2019t involved with the review.<\/p>\n

Shares of vaccine makers fell after the review was published. BioNTech SE\u2019s American depositary receipts fell as much as 7.7%, the biggest intraday decline in almost a month, while partner Pfizer Inc. dropped as much as 2.5%. Moderna Inc. also lost as much as 7.7% as of 11:12 a.m. in New York, and AstraZeneca Plc. slipped as much as 1.2% in London.<\/p>\n

The analysis is a blow to President Joe Biden, who announced his booster program in August after an extraordinary joint statement from his top medical advisers, including CDC Director Rochelle Walensky, Anthony Fauci, the longtime head of National Institutes of Allergy and Infectious Diseases, and FDA Acting Commissioner Janet Woodcock.<\/p>\n

Biden\u2019s advisers said then that the data supported the need for boosters and that they would begin preparing for them, noting that regulators would still need to sign off on the plan.<\/p>\n

Some experts have questioned the need for the extra shots, while the World Health Organization has called for a moratorium on them until more people outside of rich countries can get protection. A U.K. government advisory panel is set to soon recommend whether to move forward with broad use of a third vaccine dose.<\/p>\n

Britain is already offering boosters to those with severely weakened immune systems, as are many European Union countries. The European Medicines Agency is also reviewing booster data from Pfizer and BioNTech, and from Moderna Inc.<\/p>\n

Among the scientists behind the Lancet article were Marion Gruber, who leads the FDA\u2019s Office of Vaccines Research and Review, and her deputy Philip Krause. Both have said they would step down later this year.<\/p>\n

Gruber and Krause were two of a group of FDA staff who last year pushed back against pressure by the Trump administration to speed up the authorization of the Covid vaccines, according to a person familiar with the matter. The WHO\u2019s Soumya Swaminathan, Ana-Maria Henao-Restrepo and Mike Ryan also worked on the review.<\/p>\n

The WHO said it would make better public-health sense to focus on immunizing those who haven\u2019t gotten any shots yet \u2014 whether because of anti-vaccine sentiment in countries with ample reserves, or because they live in places with little access to shots.<\/p>\n

\u201cEven if boosting were eventually shown to decrease the medium-term risk of serious disease, current vaccine supplies could save more lives if used in previously unvaccinated populations,\u201d the authors wrote.<\/p>\n

Across the observational studies done so far, vaccination has shown an average of 95% effectiveness against severe disease, including against more infectious variants such as delta, and more than 80% effective at preventing any infection, the review found.<\/p>\n

Even in countries with high vaccination rates, it\u2019s unvaccinated people who are driving transmission of the virus \u2014 and who are at highest risk of becoming very ill, the study found. Bloomberg<\/p>\n","protected":false},"excerpt":{"rendered":"
