Drive-through vaccination clinics appear to improve the safety of individuals and communities, research has shown.
A study, which was published in the Journal of Emergency Management and is titled Drive-thru influenza immunization: Fifteen years of experience, involved a review of flu inoculations that have taken place since the programme started.
While vaccinations have been shown to have many benefits for international healthcare, some critics have claimed drive-through clinics could result in patients fainting and having car accidents.
However, the analysis, conducted by a team at University of Louisville (UofL) School of Medicine's division of infectious diseases and led by Dr Ruth Carirco, found these concerns are unfounded.
At least 50,000 doses of the flu vaccine have been given to people since the annual drive-through programme commenced in 1995 and there have not been any reports of recipients fainting or having car accidents related to the inoculation.
Despite this, the Epidemiology and Prevention of Vaccine-Preventable Diseases reference book from the US' Centers for Disease Control and Prevention mentions that influenza immunisation programmes carry the risk of people fainting.
UofL scientists stated this information is likely to be the result of inoculations in traditional settings.
When expatriate health insurance customers and other individuals receive a shot in a drive-through, they remain seated and are in a familiar location.
Statistical inferences gained from a review of legal and medical texts revealed the chance of someone fainting after having a vaccination in a drive-through was negligible.
"Some experts in the field have placed their fears about fainting risks ahead of fact and we wanted to dispel the myths," Dr Carrico remarked.
"We found a person's chance of fainting during a drive-through vaccination is less than the probability of being struck by lightning," she added.
According to Flu.gov, common side effects of the inoculation include headaches, fever and soreness.
Other more severe responses, including hives, facial swelling or difficulty breathing, require immediate medical attention, it stated.
