You should have put the actual link as well: https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety/adverse-events.html . Complete paragraph is:
Over 285 million doses of COVID-19 vaccines were administered in the United States from December 14, 2020, through May 24, 2021. During this time, VAERS received 4,863 reports of death (0.0017%) among people who received a COVID-19 vaccine. CDC and FDA physicians review each case report of death as soon as notified and CDC requests medical records to further assess reports. A review of available clinical information, including death certificates, autopsy, and medical records has not established a causal link to COVID-19 vaccines. However, recent reports indicate a plausible causal relationship between the J&J/Janssen COVID-19 Vaccine and a rare and serious adverse event—blood clots with low platelets—which has caused deaths. Get the latest safety information on the J&J/Janssen vaccine. CDC and FDA will continue to investigate reports of adverse events, including deaths, reported to VAERS.
