No, you don't have to give them vaccines. Just let them catch the virus like we did in my day. We had parties where kids were invited in the hope that they would catch the virus. Why? Because adults got much sicker if they caught the bug. Don't forget good old Rubellea. If adult women got pregnant while they were sick, the child would almost certainly be disabled. Of course, in this day and age of disposable children, the woman would just have an abortion.
There was no vaccination for whooping cough when I was young. I ended up in emergency and I was quarantined. I relapsed just after I was discharged. Back again.
Funny about masks. Asians have been wearing them for decades if they have a cold or flu. We are much more generous. We like to spread it around.
Sanitiser/soap and water - your choice. We use sanitiser for personal hygiene. If my hands are dirty from gardening and such, soap and water are fine.
