I've found in the past when you talk to people about vaccines in general is it goes like this:

There are NO side effects, you antivax moron! The side effects are very minor, EXTREMELY rare and usually temporary. Vaccines are safe and effective! (we are here). It's your moral duty to protect those who cannot be protected by vaccines! It's your DOOTY to get vaccinated to protect those who are protected by vaccines, because the vaccines are not 1000% effective! Nobody said the vaccines were 100% safe and effective! Nobody said the vaccines were safe for everyone, that's why everyone had informed consent and chose of their own free will to take the risk! Many of those classed as vaccine deaths and injuries would have died or had that issue anyway! Yes, of course some people die or are crippled, that's the risk we take to live in a safe society! Yeah, when you make an omelette you have to break a few eggs *shrug. Yeah, some people are dead or crippled, deal with it lol. The majority over-ride the minority, if we have to kill 10% of the population and cripple another 20%, that's only 30% and it's worth it to protect me and the rest of us 70%, so suffer silently rflmao!

In other words, once forced to acknowledge the deaths and injuries, they will just laugh in your face.
