Should i get at least 1 dose of an mrna vaccine if i had a mild case of covid 12 months ago?

Once you've had covid you're able to get both doses on schedule( depending on which vaccine you're receiving )when you've been quarantined 14 days but have had no symptoms for at least 10 days as your natural antibodies may be too high yet.. However if you've received monoclonal antibody treatment you must wait 90 days to get vaccinated.

Yes! Having COVID-19 only protects you from that strain for a few months. You can still get other strains annd any type of COVID strain is possible 1 year later. The vaccines will be necessary for us all for months or years to come, like flu and tetanus shots. See this CDC information page: https://tinyurl.com/5fbc5h8a
