Single dose of Pfizer or Moderna enough to prevent COVID-19 infection in two-thirds of cases, new B.C. study finds

VANCOUVER -- A new study from the B.C. Centre for Disease Control found that a single shot of Pfizer or Moderna COVID-19 vaccines reduced the risk of infection in British Columbians 70 and older by about two-thirds.

The study, which was posted this week on the BCCDC website, and has not yet been peer reviewed, also found that protection was only slightly reduced when it came to two variants of concern, the alpha variant (also known as the B.1.1.7 and associated with the U.K.) and the gamma variant (or P.1, associated with Brazil).

Researchers found vaccine effectiveness was negligible for the first two weeks after a shot.

Effectiveness increased to 43 per cent during week three, and to 75 per cent during week five, the study said.

Overall vaccine effectiveness three weeks after the first dose was 72 per cent for non-variants of concern, 67 per cent for the alpha variant, and 61 per cent for the gamma variant.

Such protection is particularly meaningful considering that it was provided during a period of peak pandemic risk, when (variants of concern) were predominantly contributing to the epidemic in BC,” wrote the study’s author, Dr. Danuta Skowronski.

Skowronski, the BCCDC’s epidemiology lead of influenza and emerging respiratory pathogens, added that she was “thrilled” and “energized” by the findings, which she said likely underestimated the protection warded by a first dose.

The BCCDC collected 16,993 specimens from adults 70 and older living in the community in British Columbia, rather than in long-term care.

It’s mind boggling how reluctant the US is to adjust dosage regimens and requirements based on age or prior infection. Part of the problem may not be the vaccines themselves but the excess dosage.

If even in the elderly, a single dose provides this much protection, how much more for the young?

Duh....how many Seniors died after the second dose. My 55 year old son in law was violently ill after the second shot.

This reads like a modified limited hangout to me, not good medical practice.

But that ship sailed a year and a half ago, didn’t it.

Are you kidding? That's not the big picture at all. It's a miniscule gain in "immunity" for young people that have far less risk from the disease, not to mention all the risk from side effects including death, and the availability of effective alternative treatments.

Not worth it to take the non-FDA approved, experimental vaccine for them.

JUST SAY NO.

My beautiful niece was hospitalized for side effects of vaccine. She doesn’t know what hit her and her father, the only sane one in the family, asked me not to tell her as he mom pushed her into getting vax. Niece will be using a walker for awhile, but will make a full recovery.

So0 sorry about your niece.

Even Fauci said the second dose of Moderna hit him like a ton of rocks and he was totally out of commission for at least 24 hours.
