Immunity offered by vaccines wanes more quickly with omicron, finds UK study
The protection conferred by booster vaccines against the omicron variant begins to wane within 10 weeks, according to a briefing released by the UK Health Security Agency .
Based on an analysis of 147,597 delta and 68,489 omicron cases, the agency found that the Oxford/AstraZeneca, Pfizer/BioNTech and Moderna vaccines are less effective against omicron than delta. For people who had two initial doses of the Oxford/AstraZeneca vaccine, the UKHSA estimates that Pfizer/BioNTech or Moderna boosters are around 60 per cent effective at preventing symptomatic infections from omicron 2 to 4 weeks after the third dose, but this falls to 35 to 45 per cent by 10 weeks. For those who had two initial doses of Pfizer/BioNTech, protection falls from 70 per cent at 2 to 4 weeks to 45 per cent at 10 weeks after a Pfizer booster, but stays around 70 to 75 per cent up to 9 weeks after a Moderna booster.
However, modelling suggests that the severity of omicron would need to be around 90 per cent lower to avoid similar levels of hospital admissions to previous waves, according to minutes from a meeting of the UK governments Scientific Advisory Group for Emergencies on Monday.

Blood Supplies Strained By Covid
Doctors the world over are sounding the alarm about limited blood supplies. Unlike in the US, some countries force potential donors to wait for a determined time period from when they have their covid-19 shot. Also, fewer are giving blood out of concern over the once again surging number of cases due to the Delta covid-19 variant.
Dr. Claudia Cohn, chief medical officer at AABB, previously known as the American Association of Blood Banks told Reuters that in the US a supply that was already stretched by the pandemic tighten even more as hospitals increased surgeries that had been on hold. The South Korea Red Cross says that it has just 3.2 days’ worth of blood on hand, less than half the supply it had this time last year.
Preparing For Your Vaccine
You can get a COVID-19 vaccine and other vaccines, including a flu vaccine, at the same visit. Experience with other vaccines has shown that the way our bodies develop protection, known as an immune response, and possible side effects after getting vaccinated are generally the same when given alone or with other vaccines. Learn more about the timing of other vaccines.
You should get a COVID-19 vaccine even if you already had COVID-19.
Getting sick with COVID-19 offers some protection from future illness with COVID-19, sometimes called natural immunity. The level of protection people get from having COVID-19 may vary depending on how mild or severe their illness was, the time since their infection, and their age. No currently available test can reliably determine if a person is protected from infection.
All COVID-19 vaccines currently available in the United States are effective at preventing COVID-19. Getting a COVID-19 vaccine gives most people a high level of protection against COVID-19 even in people who have already been sick with COVID-19.
Emerging evidence shows that getting a COVID-19 vaccine after you recover from COVID-19 infection provides added protection to your immune system. One study showed that, for people who already had COVID-19, those who do not get vaccinated after their recovery are more than 2 times as likely to get COVID-19 again than those who get fully vaccinated after their recovery.

Verify: Can You Donate Blood Platelets And Plasma After Getting A Covid Vaccine
Have you thought about donating blood, plasma or platelets lately, but recently got a COVID vaccine and don’t know if you actually can?
There’ s always a need for donations when it comes to blood, plasma, and platelets but with the pandemic coming around and rocking everyone’s world, it brings up this question.
If you’ve recently been vaccinated against Covid-19, can you donate these blood, plasma, and platelets?
DONATING BLOOD AND PLATELETS
If you’re really looking to donate something, there’s good news when it comes to blood.
Dr. Karen Landers with Alabama Dept. of Public Healh has an answer. She says, “There’s really not .You can get your vaccine today and give blood that afternoon.”
The same goes for platelets. There is no waiting time when it comes to donating them.
PLASMA vs. CONVALESCENT PLASMA
Let’s focus on something called convalescent plasma, which got a lot of publicity at the height of the COVID-19 pandemic as a possible treatment for the virus.
Kami May, Community Development Coordinator for LifeSouth, says, “We are no longer accepting convalescent plasma from those who have received the vaccine only because that is considered artificial antibodies.”
She also says that there is simply not enough research out there when it comes to these kinds of plasma donations and the vaccine.
DOES DONATING AFFECT MY VACCINE STATUS?
Donating Plasma After Covid
U.S. FDA refines its recommendations, says vaccinated people may donate convalescent plasma under certain criteria.
As more people in the United States get the COVID-19 vaccine, U.S. regulators have updated the rules about who can and cannot donate convalescent plasma intended as a COVID-19 treatment.
Donors who have been vaccinated against COVID-19 can still donate source plasma.
Whats the difference?Source plasma is used to make treatments for people with rare and serious diseases. Convalescent plasma is collected from people who have recovered from COVID-19 for the antibodies against the virus.
Previously, the U.S. Food and Drug Administration said COVID-19 vaccine recipients could not donate convalescent plasma. But recently, the FDA updated those recommendations to say that vaccinated people may donate convalescent plasma if they:
- had symptoms of COVID-19 and a positive test result from a diagnostic test approved, cleared, or authorized by FDA
- received the COVID-19 vaccine after diagnosis of COVID-19
- are within six months after complete resolution of COVID-19 symptoms
This is to ensure that COVID-19 convalescent plasma collected from donors contains sufficient antibodies directly related to their immune response to COVID-19 infection, according to the guidance.

Latest Coronavirus News As Of 12pm On 7 January
The potentially massive scale of unrecorded covid-19 deaths in Indias second wave means the official world death toll may be a significant underestimate
Indias death toll from covid-19 may be six to seven times greater than that officially recorded. The countrys records say that nearly half a million people have died from coronavirus infections so far, but thelatest study estimates the real figure is 3.2 million deaths up to July last year.
If correct, this means the worldwide death toll from the coronavirus would be pushed up from 5.4 to 8.1 million although other countries may also have underestimated their death rates. This may require substantial upward revision of the World Health Organizations estimates of cumulative global covid mortality, Prabhat Jha at the University of Toronto and colleagues say in their paper.
India experienced ahuge second wave of coronavirus infections in the first half of 2021, leaving hospitals overwhelmed and a national shortage of oxygen supplies. In common with many other low and middle-income countries, India does not have good systemic methods for recording causes of death, especially those that occur in rural areas. For instance, Jhas team say that in 2020, an estimated eight in ten deaths did not involve medical certification, which is standard procedure in richer countries.

Coronavirus Vaccine Could Affect How You Donate Plasma
BATON ROUGE, La. – While the COVID-19 vaccine may offer hope to communities across the country, it could cause a snag for COVID-19 patients who are receiving plasma treatment.
If you are a recipient of Pfizer or Moderna COVID-19 vaccine, that pretty much makes you ineligible to donate any future convalescent plasma to any people that are struggling with COVID-19 right now, said Michael Pena with Blood Share in Baton Rouge.
Pena says survivors of COVID-19 can donate their plasma and help save a critical life who is suffering from the virus. But now, with many already receiving the COVID-19 vaccine, there could be a shortage of plasma, with survivors not being able to donate.
When you get the vaccine it wipes out the antibodies that your body has developed when that person had covid-19 before, so it helps you but if you intend to try to help other people by donating your plasma then it negates it, Pena said.
In a study back in June, more than 20,000 COVID-19 patients in the us were treated with the plasma, and that number continues to rise. Pena says in order to provide for those who need this plasma, COVID-19 survivors need to donate as much as they can before getting the vaccine.
