[Asia Economy Reporter Hyunwoo Lee] It has been reported that some clinical trial participants dropped out during the clinical trials of the COVID-19 vaccine being developed by pharmaceutical company Johnson & Johnson. The participants demanded detailed information about the risks of the vaccine after news broke about side effects from AstraZeneca's COVID-19 vaccine, and some refused to continue and dropped out. As concerns about the vaccine's safety grow, prospects for its release within this year are diminishing.


According to foreign media such as CNBC, on the 15th (local time), La Paz Hospital in Spain announced that some participants dropped out during the clinical trials of the COVID-19 vaccine developed by Johnson & Johnson. The hospital stated that the participants requested detailed information about the risks of the vaccine, but they could not disclose how many participants dropped out. It is known that the participants' fear increased after news emerged about transverse myelitis side effects during AstraZeneca's clinical trials conducted in the UK.


Johnson & Johnson stated that although some participants dropped out in Spain, they have a sufficient pool of participants to continue the clinical trials normally, and if phases 2 and 3 proceed smoothly, the vaccine could be released to the market as early as the beginning of next year.



Previously, Johnson & Johnson announced that its subsidiary Janssen began phase 2 clinical trials of the COVID-19 vaccine on 190 people in Spain starting from the 14th, and results were expected as early as the 22nd of this month. Johnson & Johnson also stated that clinical trials are ongoing in the Netherlands and Germany, with a total of 550 participants across the three countries.
