Yes. There are several COVID-19 vaccines validated for use by WHO (given Emergency Use Listing) and from other stringent national regulatory agencies (SRAs). The first mass vaccination programme started in early December 2020 and the number of vaccination doses administered is updated on a regular basis here.
It's important to note that the availability of specific vaccines may vary by country or region, and different vaccines may have different efficacy rates or recommended dosing schedules. It is advisable to consult with local health authorities or healthcare providers to get the most up-to-date and accurate information about COVID-19 vaccines in your area.
It's also worth mentioning that vaccination is an important tool in controlling the spread of COVID-19, but it's not the only measure. Following public health guidelines, such as wearing masks, practicing good hand hygiene, maintaining physical distance, and staying informed about local guidelines and restrictions, are also crucial in preventing the spread of the virus.
