first of all if your original vaccines, you get the vaccine, made by pfizer or moderna. if you have gotten pfizer where you re going to get pfizer when you go to the pharmacist or the doctor, where then you need to be 12 or older. for the moderna version of the same vaccine, you need to be 18 or older. and you need to be at least two months after your last shot and that goes where you have the primary or a single booster already. in another case, waiting at least two months and it could be longer, it could be up to six months, however, julián, if you ve had risk factors like you re an older person or you re immunocompromised or chronic illness, you may need to get your shot sooner rather than later. that s four left the general.
