Vaccination must be done at proper vaccination centre with all equipment ready to treat reaction ( which is rarely occurred but when happen it is life-threatening).
So I discourage home vaccination. Also vaccination is not just give injection, it is fully organized process.
Next Steps
consult pediatrician, take appointment for vaccination ( so there will not be crowding at clinic) , teleconsultation before going to hospital for routine queries ( so you are not be in clinic for more time).
Health Tips
Most pediatrician are taking all precautionary measures for your safety.
at clinic , maintained physical distance, good hand hygiene and compulsory wear mask.
