Anyone in Lebanon who received a third dose of the coronavirus vaccine more than six months ago can now get a fourth, without an appointment, authorities announced on Wednesday, as the overall two-dose vaccination rate in the population remains below 45 percent, almost two and a half years after the appearance of the pandemic in the country.

"Based on scientific recommendations, it is now possible for anyone who received a third dose of vaccine more than six months ago, to benefit from a fourth, without an appointment, according to the walk-in procedure," the Health Ministry announced in a press release. However, the ministry did not specify which centers or hospitals offer this possibility.

Less than 50 percent of the population in Lebanon has received a first dose of vaccine against COVID-19. In Lebanon, the coronavirus has caused more than a million contaminations and more than 10,000 deaths since February 2020.
