Just a headsup in case you got your Astra dose at Phayathai 2 hospital. I did on July 27. At that time I got a slip saying my date for the next dose is Oct. 19. Today got an SMS saying it's Sep. 30. Contacted the hospital and they confirmed that the date has been moved forward.

I got the same notification.

 

To quote The Lancet:

 

"The study found that leaving less than 6 weeks between the initial shot and the booster gave a 55.1% efficacy. Leaving 6-8 weeks between shots increased efficacy to 59.9%, and waiting 9-11 weeks, efficacy was 63.7%. However, if the gap was 12 weeks or longer, efficacy jumped to 81.3%"

 

What's going on here Thailand...why are you moving me from 81.3% efficacy to 63.7% efficacy...?

 

I do not like this...!

 

 

PS This is for the Astra Zeneca Vaccine.

The same thing has happened in a number of countries experiencing outbreaks (I thought even the UK, though I could be mistaken). You get a lower efficacy, but you get it right now, and it's still much better protection than what you're getting from the single dose you already received. Waiting an extra month to get better efficacy from the second dose leaves you more vulnerable in the meantime, which may be undesirable if the virus is running rampant in your area. It's just a trade-off.

Well Khun Jeff,

 

Interesting point, and therefore...trade-off. What to do? I was fully psychologically and physically prepared to wait the full 12 weeks, being very diligent in my self-protection efforts.

 

 

My 2nd dose also got moved forward three weeks.  Notification arrived by text message.

And are you okay with losing just under 18% of your efficacy...?

Question: How many weeks is it from July 27 to Sep. 30?

 

Answer: 9.3 weeks

 

What's your beef?
