Coronavirus

COVID-19: Evidence suggests that new variants could pose challenge for vaccines

The research findings show that the new COVID variants may likely not respond well to the vaccines.

Recent research findings suggest that the new coronavirus variants would likely pose a big challenge for the vaccines, as revealed by studies by several medical researchers.

The new variant was first discovered in South Africa in October but has now been spread to more than a dozen countries all over the world.

According to the most recent findings, as reported by CNN, researchers took antibodies from six people who were hospitalized with Covid-19 before the new variant was discovered. They found to varying degrees, that the antibodies for all six of the survivors were unable to fully fight off the virus.

According to Alex Sigal, a virologist at the Africa Health Research Institute and the Max Planck Institute for Infection Biology, “I think the evidence is building that these mutations — and I think other mutations — will emerge across the globe — and are emerging already — that are escaping antibodies from previous infection. It’s concerning.”

According to Jesse Bloom, a virologist at the Fred Hutchinson Cancer Research Center, “When you see two groups independently arriving at same basic answer, that good — there’s more consonance that they are correct”

What you should know

  • Sigal’s findings were very similar to those of a recent study by the National Institute for Communicable Diseases in South Africa.
  • A research study has revealed that mutations in the new variant allowed them to evade some of the immunity induced by vaccination, but it was far from a complete escape.
  • One thing that is critically safe for everyone is to get vaccinated, while the researchers are working to confirm whether these variants are dangerous or not to contain with the vaccines.
  • According to Alex Sigal, “I would for sure get it if I could. My father-in-law had the opportunity to fly to Israel and get it, and I was shooing him out of the house because you can’t get it here in South Africa.”
  • In a research study done at Rockefeller University, from a sample of 20 people who had received either the Moderna or the Pfizer vaccine, it was found that different mutations in the viruses did allow some escape from some types of antibodies, but the volunteers’ immune systems threw an army of different types of antibodies at the viruses.
  • According to the research conducted in South Africa, blood was drawn from 44 people who had Covid-19 but the antibodies of about half of the 44 people were powerless against the new variant, while the other half, their antibody responses were weakened, but not totally knocked out.

The Federal Government has announced that President Muhammadu Buhari and Vice-President Yemi Osinbajo, will receive shots of AstraZeneca/Oxford COVID-19 vaccines on Saturday to demonstrate vaccine safety to the public.

This follows the country’s receipt of the first batch of about 4 million doses of the AstraZeneca Covid-19 vaccine under the COVAX initiative and the planned launch of the national vaccination campaign.

This disclosure was made by the Executive Director of National Primary Health Care Development Agency (NPHCDA), Dr Faisal Shuaib, at the second edition of the State House briefing in Abuja on Thursday, which is focused on Nigeria’s response to the Covid-19 pandemic and the country’s national vaccination strategy.

He said that the exercise will boost the confidence of Nigerians to receive the about 4 million doses of AstraZeneca/Oxford Covid-19 vaccine that arrived in the country 2 days ago.

Shuaib said, “The next step in the vaccination programme given that we’ve now received the vaccines is a launch that will be taking place at the National Hospital tomorrow. The time scheduled for that launch is 10 am. The launch will be conducted by the Chairman of the Presidential Task Force on COVID-19, (Boss Mustapha).

“The plan is to vaccinate the frontline health workers that work in the treatment centre of the National Hospital, those will be the first people just like we’ve communicated that frontline health workers will be the first people to take the vaccines.

“Launch of National vaccination campaign will take place at the National Hospital Abuja, Friday, March 5, 2021, with Frontline health workers.

On Saturday, the plan is to vaccinate Mr President, Mr Vice-President and strategic leaders, to demonstrate vaccine safety to the public.

 Again, we are hopeful that when Nigerians see leaders like Mr President and Mr Vice-President take the vaccines; it will increase their confidence around the safety of the vaccines.

“As you are well aware that even before the vaccines arrived in Nigeria, there is a lot of hesitancy. It is a global phenomenon. Vaccine hesitancy is similar no matter where you are, you have to provide the right information and to those people who have questions, we cannot dismiss their cynicism.’’

The NPHCDA boss also said that state governments must certain requirements and obligations before the Covid-19 vaccines will be released to them.

He said, ‘’States have requirements and obligations to fulfil before the Covid vaccines will be released to them. They have to demonstrate they have taken steps to ensure proper storage, security, etc.’’

What you should know

  • It can be recalled that the much-awaited AstraZeneca/Oxford vaccine arrived at Nnamdi Azikiwe International Airport Abuja around noon on Tuesday, March 2, 2021, onboard an Emirates airline.
  • The receipt of the 3.92 million doses of the vaccine is the first batch from the over 16 million doses allocated to Nigeria through the COVAX initiative, aimed at vaccinating about 20% of the population.
