If you are eligible and have not received a Covid-19 vaccine, please do get vaccinated immediately.
The vaccine is safe and effective and prevents serious illness and hospitalization if you develop Covid-19 after vaccination (an uncommon occurrence). Even if you have had Covid in the past, you should still get vaccinated. By getting vaccinated you are helping to stop the spread of future Covid variants and helping to keep yourself and your families safe.
