I'm concerned about boosters being 3 monthly, my period vanished for months after my first/second dose. I know several people who missed up to 3 months period after getting vaccinated and one whose only bled very lightly since. I know that's anecdotal, but a quick google and read of some of the threads on here show a proven link between vaccination and changes to your cycle.
It's one thing to ask young women to accept this once a year, but every 3 months could result in cycle changes almost constantly which is worrying to those who are trying for kids or want to one day, and those who track their cycle for contraceptive purposes. I wouldn't be willing to get a booster every 3 months for this reason.
Is this valid? I work in the NHS, not patient facing, and I'm pro vaccine and was happy to be vaccinated but cannot deny that it did make temporary changes to my cycle and I'm not willing for that to be ongoing? Would an employer see this as fair?
