Kenyan gets Covid jab as US declares Moderna effective
PD Reporter and Agencies
Pulmonary and critical care specialist Dr Stella Biyaki Ogake received her Covid-19 vaccine at the OSU Wexner Medical Centre in Ohio, US, on Monday.
“For us who are on the front lines taking care of these patients, it is such a moment of hope because we can see the light.

We can see the end of this pandemic,” she told CNN. “When I saw the truck coming out of the Pfizer manufacturing plant yesterday, I was so emotional just thinking about all the work that we had to put in to get here,” she added.
Getting the vaccine alleviates her fear of getting the virus or taking it home to her family, she said, adding she wants this moment for other Americans too.
“Just seeing patients in the hospital and seeing what they go through, my biggest fear is getting it myself or taking it home to my son or my husband, or my other family members.
And for them to get as sick as the people I take care of, that’s definitely my biggest fear,” she said Monday.
Right after taking the vaccine, she said she was feeling good and it wasn’t painful.
Dr Ogake graduated from Moi University College of Health Sciences in 2008 and worked at the Aga Khan University Hospital in Nairobi until 2012 before relocating to the US where she is an assistant professor.
And yesterday, the US regulator released new data confirming Moderna’s Covid-19 vaccine was safe and effective, a strong sign that it could receive emergency approval in days and be ready to roll out by next week.
The Food and Drug Administration said there were “no specific safety concerns identified that would preclude issuance of an EUA (emergency use authorisation)” and confirmed an overall efficacy of 94.1 per cent.
Distribution of the Pfizer-BioNTech vaccine began on Monday and if the FDA green lights Moderna’s, rollout of some six million doses could start next Monday.
That would represent a powerful second weapon against the virus in the worst-hit country in the world, where more than 300,000 people have died from Covid-19 and a winter surge continues across much of the country.
The FDA document offered the clearest look yet into the Moderna vaccine, which was co-developed with the National Institutes of Health (NIH).
This came as CNN reported that New York City has already administered 73 first dose vaccines to health care workers, quoting Mayor Bill de Blasio yesterday.
Nearly 41,000 more doses are expected to be available by the end of the day at 42 hospitals.
It reported that frontline healthcare workers and nursing homes remain top priority.
“This is going to really speed up,” he said, calling it “incredibly encouraging.”
On Thursday, an independent group of scientists will convene to debate everything known so far about the product, which Moderna and the NIH began developing in January using cutting-edge mRNA technology.
The panel is expected to vote in favor of an EUA, and the FDA normally acts upon its recommendations.
According to the new data release, the two-dose regimen protected younger people slightly better than it did older people.
In a clinical trial of 30,400 people, 196 fell ill with Covid-19 by November 21 — 11 in the vaccine group and 185 in the placebo group.
Efficacy was 95.6 percent for people aged 18-65; 86.4 percent among those aged 65 and older; and 94.1 percent overall.
Importantly, of 30 cases of severe Covid-19, all occurred in the placebo group.
The FDA also looked at detailed safety data, at a median of nine weeks after participants had received the second shot, which is taken 28 days after the first.
The most common side effects associated with the drug, called mRNA-1273, were injection site pain in roughly 90 percent of cases; fatigue in 70 percent, headache in 60 percent, muscle pain in 60 percent, joint pain in 45 percent and chills in 45 percent.
Few of these effects were classed as “severe” and when they were that tended to occur more in the young than in the old.
Lymphadenopathy, or swollen lymph nodes occurred in 1.1 percent of the vaccine group compared to 0.6 percent of the placebo group.
There was an imbalance in allergic or inflammatory reactions by the immune system -- which occurred in 1.5 percent of the vaccinated population compared to 1.1 percent of the non-vaccinated.
But there were none that were classed as severe or anaphylactic.
Throughout the follow-up period to date, there have been three reports of Bell’s palsy -- a facial paralysis condition -- in the vaccine group and one in the placebo group.
The Pfizer trial saw four people get Bell’s palsy in the vaccine group, and none in the placebo group.
In both cases, the FDA said there was insufficient information to determine that the vaccine was the cause of this paralysis, which normally resolves within three months.
Andrew Morris, a University of Toronto professor of medicine who has studied the condition, told AFP however “it is becoming increasingly likely that there is an important relationship with Bell’s (facial) palsy.” “The absolute risk -— in light of the risks associated with Covid-19 -— is small,” he stressed.
The frequency of life-threatening events was low, around one percent in each group, and there was no suggestion that the vaccine was the cause.
Both the Pfizer and Moderna vaccines use mRNA (messenger ribonucleic acid) which makes human cells express a surface protein of the new coronavirus.
This simulates an infection and trains the immune system to be ready in case it encounters the real virus.
The mRNA is encased inside fatty particles.
Both companies used a slightly different formulation resulting in different cold-storage requirements: -70 degrees Celsius (-94 degrees Fahrenheit) for Pfizer; -20 degrees Celsius (-4 Fahrenheit) for Moderna.
The US hopes to immunize 20 million people this month, with health care workers and long-term care residents at the front of the line.
Authorities want to reach the rest of the population by summer, but much will depend on vaccine confidence. Experts estimate more than 70 percent of people will need to be vaccinated to bring the outbreak to a close. - AFP & CNN
