Booking vaccination appointments against Covid-19 for citizens aged 60-64
The online platform for booking vaccination appointments against Covid-19 for citizens aged 60-64 will open on Wednesday February 10.
Two days later, on February 12, the platform will open for citizens aged 75-79.
Speaking alongside Health Ministry Secretary General for Primary Health Care Marios Themistokleous, Professor Maria Theodoridis, Head of the National Vaccination Committee, said that the AstraZeneca coronavirus vaccine is "safe, offers immunization and is effective in ages 18 and above."
She added that the committee looked into all the scientific data before deciding not to have it administered to anyone over the age of 65, but she did explain that "bearing in mind the small number of participants, the committee might decide otherwise according to potential new data."
The vaccine will be given to anyone aged between 18 and 64, in two doses taken 12 weeks apart.
