>130000 vaccines were administered May 4, and >133000 today so far.
>40% of adults in ON have received a 1st dose.
Some thoughts about the past & future weeks👇
2/ People came out in droves for AstraZeneca when the age limit dropped to 40. We had a lot of AZ in the freezer at that time & now there is not much left.
(Much has been said about AZ since then. I am happy for people who received it)
3/ AstraZeneca administered via ~1400 pharmacies & primary care (family doctors & nurse practitioners) pushed our daily vaccine rate to over 130K/day. The pace slowly dropped as supply diminished.
AZ use significantly dropped yesterday & today, likely driven by public discourse.
4/ The fast pace of overall vaccination yesterday & today is largely driven by Pfizer & to a lesser extent Moderna, through:
1) Mass vaccine clinics 2) Pop-up & mobile clinics
This is an impressive pace, especially given the lower rates of AZ administered via pharmacies.
5/ We are getting a ton of Pfizer this month & beyond. Moderna is also starting to pick up.
Pharmacies are starting to administer Pfizer & will expand. Primary care is administering AstraZeneca & will likely expand their use of Moderna as well.
11/ Areas for improvement in Ontario's vaccine rollout:
*Expansion of primary care involvement, province-wide
*Cumbersome sign-up system
*Expansion of Pfizer in pharmacies
*More frequent communication & better transparency
*Other/etc.
12/ Also, just because various groups are eligible to sign up, it does not mean they will be vaccinated imminently.
In May we get ~800K doses of Pfizer per week & ~800K doses of Moderna total. That's a lot of vaccine but not enough for all of us.
It will take a bit more time.
13/ 2nd doses:
It is likely (not guaranteed) that many will receive 2nd doses before the 4 month mark due to greater supply.
Also, we can likely start to vaccinate the 12-16 year age group perhaps sometime in the early summer, well before school.
14/ **Total speculation here** For those who received a 1st dose of AstraZeneca, there may be an option to receive a 2nd dose of Pfizer given 1) stable/large supply of Pfizer, less so with AZ, 2) pending results of COM-COV study in the UK.
Ontario has vaccinated >130000 people per day May 4, 5 & on track for this today too.
Over 40% of adults in the province have received at least 1 dose.
Some details on past few days & next few weeks 👇
2/ We doled out a ton of AstraZeneca when eligibility dropped from 55 to 40 yrs, but then ⬇️ supply led to ⬇️ pace of AZ vaccination.
Currently there is very little AZ administered this week following recent public discourse.
I am happy for those who received this vaccine.
3/ Equity of vaccine administration was an issue earlier in April. There is ongoing prioritization of supply to heavily impacted neighbourhoods & it's working.
This graph was when 25% of vax supply went to hot spots.
Now hot spots get 50% of supply for the next 2 weeks.
1. "Health Minister Patty Hajdu says her government embraces the concept of 'vaccine passports' & will come up with a form of certification to allow vaccinated Canadians to travel internationally."
2/ NACI outlines protection after 1 dose of a vaccine in their recent document:
"Most importantly, these studies show one dose of the Pfizer-BioNTech & AstraZeneca vaccines are
approximately 80% effective against hospitalization..."
A few points to clarify vaccine distribution in Ontario.
1. We get ~400K doses of Pfizer weekly. It shows up like clockwork. It gets distributed throughout the province in ~1-2 days & there is very little at the end of the week. This is administered at mass vaccine clinics.
2. We get several hundred thousand doses of Moderna every 2 weeks. Also rapidly shipped to locations in the province. For various reasons, Moderna shipments are occasionally delayed. There is very little Moderna in freezers at the end of the 2 weeks.
3. We have infrequent large boluses of AstraZeneca. This is administered by primary care in 6 Public Health Units, and by ~1400 pharmacies throughout the province.
It is available to anyone 55 years of age and older.
