Netizens who received the Janssen COVID-19 vaccine donated by the U.S. government are posting reviews on online communities and social networking services (SNS), drawing attention. Unlike the Pfizer and AstraZeneca (AZ) vaccines, the Janssen vaccine is completed with just one dose, and it was very popular, with all slots fully booked on the day of pre-registration.

On the 10th, certification photos and review posts from those who received the Janssen vaccine flooded popular SNS platforms such as Facebook and Instagram, as well as various online communities.

A netizen who completed vaccination that morning said, "The injection didn't hurt much," but added, "Right after getting the shot, my arm felt stiff. After 30 to 40 minutes, I felt weak all over."

Another netizen complained, "It was worse than the flu." However, they added, "After an hour, I felt tingling and tired, but there were no other issues," and said, "I was very nervous after reading online reviews saying people suffered as if they were dying, but I was worried for nothing."

Posts hoping for incentives such as overseas travel after vaccination also continued. One netizen, who said they were resting after getting vaccinated, expressed, "Now that the vaccination is complete, I am most curious whether overseas travel will be possible this summer," and added, "I hope to enjoy a summer vacation."

Many netizens also asked whether it is possible to take a 'shower' after vaccination. According to vaccination precautions, it is recommended to avoid intense exercise, alcohol consumption, and bathing or showering on the day of vaccination and the following day.

Meanwhile, the U.S. government and U.S. Forces Korea previously donated about 1.01 million doses of the Janssen vaccine to South Korea. These vaccines arrived at Seoul Airport on the 5th, loaded on an Air Force air refueling transport plane.

The vaccine, produced by Janssen, a vaccine division subsidiary of the global pharmaceutical company Johnson & Johnson (J&J) headquartered in the U.S., is made using a viral vector method similar to the AZ vaccine. It involves injecting vaccine material into a harmless virus template such as an adenovirus, which delivers it inside the human body to generate antigen proteins. However, the difference from other vaccines is that vaccination is completed with just one dose.

Approximately 3.7 million people are eligible for the Janssen vaccine, including about 538,000 reservists aged 30 and over, about 3.04 million civil defense personnel, and about 137,000 people related to defense and diplomacy.

Meanwhile, interest in Janssen was so high that the reservation site server crashed from the time of booking. On the first day of reservation, the 1st, the number of reservations exceeded 800,000, and pre-registration was closed early.
