AstraZeneca jabs: 8,439 mild, adverse events recorded in Nigeria – NPHCDA


The National Primary Health Care Development Agency (NPHCDA) has said a total of 8,439 mild adverse events following immunization (AEFI) had been reported since vaccination began in March.

Dr. Faisal Shuaib, the executive director and CEO, NPHCDA, said this at a press conference by NPHCDA and World Health Organisation (WHO) on Friday in Abuja, on the status of the COVID-19 vaccination in the country.

“Out of over a million persons given the Oxford-AstraZeneca COVID-19 vaccine in Nigeria, 8,439 persons have suffered mild Adverse Events Following Immunisation (AEFI), and 52 persons moderate to severe adverse events on receiving the jab.

“While the mild reactions include body pains and swelling, the moderate to severe adverse events presented were fever, vomiting, diarrhea headaches, dizziness and allergic reactions,” he explained.

Shuaib said there had been no death from the administration of the vaccine and no case of blood clots related to the administration of the vaccines in the country.

Shuaib further said five states had the highest records of the AEFI namely: Kaduna (970) Cross River (859), Yobe (541), Kebbi (511) and Lagos (448).

He said these cases were being investigated to ensure they were caused by vaccination. Shuaib restated that there was currently a global shortfall of COVID-19 vaccines, forcing the federal government to reassess vaccine supply forecasts.

He said this prompted the decision to ensure that everyone who had taken the vaccine in the current phase received the second dose before the next consignment was delivered to Nigeria.

“Furthermore, as a result of this overall program review to meet the challenges of global vaccine demand and supply mismatch, and the late commencement of the vaccination in some states, we are expanding the eligibility period between the first and second doses of the vaccine from 12 weeks to between eight to 12 weeks.

“This is still in line with the scientific recommendation provided by the World Health Organisation’s Strategic Advisory Group of Experts (SAGE on immunization) that the two doses of the vaccine be given at an interval of 8 to 12 weeks,” he explained.

The NPHCDC boss also said the administration of the first 3.94 million doses of the vaccines received from COVAX would end before its expiration in July.

On vaccine acceptability,  he explained that the NPHCDA planned to engage more at the community levels across the country, by organizing zonal town hall meetings across all geopolitical zones to facilitate the discussions around COVID-19 vaccination in Nigeria from 20th April.

Speaking on the development, the country representative, World Health Organisation (WHO), Dr Walter Kazadi, reiterated that the benefits of taking the Oxford-AstraZeneca vaccines far outweighed the risks.

He noted that over 200 million cases of AstraZeneca vaccines had been administered globally.

On vaccine availability and equity, Kazadi said the WHO was currently pressuring wealthy countries hoarding the vaccines to release them so that they could redistribute doses and make them available through the COVAX mechanism or through bilateral agreements to countries that needed them the most.

He added that WHO was all engaging the manufacturers for technology transfer, so as to have more sites that could manufacture the vaccines and scale up production.

The country representative emphasized the need for Nigeria to follow the vaccination plan to ensure that priority groups were prioritized.

It would be recalled that Nigeria kicked off vaccination on March 5, 2021, starting with healthcare workers who are mostly at risk of infection. TH Nigeria Centre for Disease Control, NCDC, noted that the vaccine roll-out would be in four phases, starting with health workers, frontline workers, COVID-19 rapid response team, laboratory network, policemen, petrol station workers and strategic leaders.

According to NAPHCDA, as of April 15, just 1,051,096 shots had been administered in 36 states and the Federal Capital Territory (FCT). It noted that the proportion of eligible people vaccinated in the country was 52. 2 percent as of April 15.
