Paris: France's health watchdog on Tuesday recommended a third dose of the Covid-19 vaccine for people aged over 65 or considered at risk of developing serious forms of the disease.
The advice from the HAS watchdog was for people who had already received two vaccine doses, who will now be offered an mRNA vaccine such as the ones produced by Pfizer or Moderna, which France has ample supply of.
Last month, the French health ministry announced a booster shot for around five million of the most vulnerable people, including those in retirement homes.
In its statement, the HAS suggested widening the criteria for those eligible for a third shot while adding that the "priority for the next few weeks is to increase vaccination coverage in particular in the 80+ age group where vaccination coverage remains insufficient (at 79.9 percent)."
France is averaging around 20,000 new Covid-19 cases a day, with the return of schools next week after the summer holidays raising concern about a new surge in infections.
The World Health Organization has called for a moratorium on booster shots until at least the end of September in order to address inequalities in global dose distribution.
Israel became one of the first countries to begin administering booster shots at the end of July after a spike in new cases.
With an open economy and most curbs scrapped, Israel went from single-digit daily infections and zero deaths to around 7,500 daily cases last week, 600 people hospitalized in serious condition and more than 150 people dying in that week alone.
On July 30, it began administering a third dose of the Pfizer/BioNtech vaccine to people over 60, the first country to do so. On Thursday it expanded eligibility to 30-year-olds and up whose second dose was given at least 5 months prior, saying the age may drop further.
In the past 10 days, the pandemic is abating among the first age group, more than a million of whom have received a third vaccine dose, according to Israeli health ministry data and scientists interviewed by Reuters.
The rate of disease spread among vaccinated people age 60 and over - known as the reproduction rate - began falling steadily around Aug. 13 and has dipped below 1, indicating that each infected person is transmitting the virus to fewer than one other person. A reproduction rate of less than 1 means an outbreak is subsiding. https://tmsnrt.rs/3grj7kv
Scientists said booster shots are having an impact on infections, but other factors are likely contributing to the decline as well.
"The numbers are still very high but what has changed is that the very high increase in the rate of infections and severe cases has diminished, as has the pace at which the pandemic is spreading," said Eran Segal, data scientist at the Weizmann Institute of Science and an adviser to the government.
"This is likely due to the third booster shots, an uptake in people taking the first dose and the high number of people infected per week, possibly up to 100,000, who now have natural immunity," Segal said.
After reaching one of the highest per-capita infection rates in the world this month, the question now is whether Israel can battle its way out of a fourth outbreak without imposing another lockdown that would damage its economy.
Evidence has emerged showing that while the vaccine is still highly effective in preventing serious illness, its protection diminishes with time. But there is no consensus among scientists and agencies that a third dose is necessary, and the World Health Organization has said more of the world should be vaccinated with a first dose before people receive a third dose.
The United States has announced plans to offer booster doses to all Americans, eight months after their second vaccine dose, citing data showing diminishing protection. Canada, France and Germany have also planned booster campaigns. -- Agencies
