How to get 3rd booster for Japan travel?

[futuremoneyinbank]

Hoping someone can help as currently I'm stuck! I've had 2 vaccinations and not been invited in for a third, so can't "ask" for one; not in a vulnerable group etc. On the Visit Japan Website they ask for proof of 3 boosters... Does anyone know how I manage this?

If you cant get a 3rd vaccine then the .gov website says you can do a PCR instead:

If you are not triple vaccinated
There is no requirement to be vaccinated in order to enter Japan, however if you cannot prove you are triple-vaccinated with any of the COVID-19 vaccines on the Emergency Use List of the World Health Organization (WHO), then you must take a PCR test within 72 hours before your flight and show a negative certificate in the approved format.

Thank you - i'll have to do that for my daughter anyway so I'll just do myself also.
