Flu vaccination in children study?

[knopk@]

I just received a letter saying we are invited to take part in this study, even more vaccinations! They are trying out new vaccine on children which has 4 virus strains( ones we get has 3) plus they mentioned chicken pox and hep a.
I will be saying no but wondering if anyone has received the same letter?
Tapatalking so cant see signatures
