The 70% is way over the top although I think the number of initial vaccinations is accelerating rapidly as is the second jab.
I had my first jab last Thursday thru' the Phitsanulok provence government system, it was Sinovac - not my choice or preference but put me into the line for Astra Z on 1st September, I can now bide my time for a 3 jab in the future when avaible to suit myself.
The vaccination procedure was flawless, extremely well organised and smooth sailing, although I needed my wife there to help navigate the system, being the only non-Thai during the time I was there and possibly one of the first, if not the first thru' their system.
