The French Supreme Health Authority (HAS) has recommended that only one dose of the COVID-19 vaccine be given to those who have already been infected with the coronavirus.
“According to the information available at this stage, people who have already been infected (COVID-19) retain immune memory. This lead HAS to offer only a single dose (of vaccine) to people infected with SARS-CoV-2, regardless of how long ago the infection occurred. Thus, the single dose of vaccine will act as a reminder,” according to a communiqué on the French regulator’s website.
The document notes that people who have been diagnosed with a coronavirus infection, whether they had symptoms or not, can be considered protected by post-infection immunity for at least three months. “But current data do not allow a judgment of immune response after more than six months. Therefore, HAS recommends vaccination about six months later (after infection) and confirms that it should not be performed earlier than three months after infection,” the press release noted.
The vaccination campaign in France began on December 27, 2020. More than 2.1 million people have received the first dose of the vaccine, according to the latest figures cited by the country’s health ministry. More than 500,000 French people received two injections
