Amid the pandemic and a resultant vaccination drive in countries all around the world, there are reports of severe reactions from one vaccine. Many states in the United States have temporarily shut down vaccine sites after people reported adverse reaction to a vaccine.

Around 18 people in North Carolina and 11 people in Colorado complained about feeling dizzy, nauseous and fainting, after taking the Johnson & Johnson vaccine. This was reported by Xinhua news agency.

After the first two, Georgia was the third US state to shut the vaccination site temporarily. In Georgia, eight people complained of side effects. Following the complaints, most people were sent to the hospital and are currently being monitored for any severe reactions.

The US Centers for Disease Control and Prevention (CDC) said its analysis "did not find any safety issues or reason for concern." Following this, the agency also recommended that healthcare providers should continue to administer the Johnson & Johnson vaccine.

Apart from the reactions, Johnson & Johnson are also facing problems with vaccine distribution in the US. This discrepancy is caused by the production issues at a facility in Baltimore, Maryland according to federal official data. The supply of the vaccine is also expected to drop by 85 per cent this week.

The delay was reportedly caused because a subcontractor mixed ingredients from the vaccine produced by Johnson & Johnson and AstraZeneca. But this was because the manufacturing plant is run by Emergent BioSolutions, a manufacturing partner to both Johnson & Johnson and AstraZeneca.

The officials regarded the mistake as human error, which led to the contamination of up to 15 million doses of Johnson & Johnson's vaccine.

The White House Covid-19 coordinator Jeff Zients announced that the company was working to address the issues in Emergent BioSolutions, which is not certified yet by the US Food and Drug Administration (FDA).

The Johnson & Johnson's Covid-19 vaccine was given emergency approval in the US following the increasing caseload and the need for a vaccine. It is also the first single doze vaccine available in the United States.

Before the temporary shut down, around 189 million Covid-19 vaccine shots have been administered in the US. Additionally, more than 237 million Covid-19 vaccine doses have been distributed across the country, according to data from the CDC.
