According to the World Health Organization, vaccines reduce the transmission of the Delta variant of COVID-19 by 40 percent.
The World Health Organization (WHO) informed Wednesday that COVID-19 vaccines reduce the transmission of the dominant Delta variant of COVID-19 by about 40 percent, reminding people not to fall into a false sense of security regarding receiving the shots.
According to WHO Director-General Tedros Adhanom Ghebreyesus, several vaccinated individuals become complacent and wrongly think that receiving the jab means they no longer need to continue taking other health precautions.
The health official also insisted that fully-immunized people should continue to stick with health measures to avoid getting infected with the virus and possibly infecting others, as well. He emphasized how more transmissible and contagious the Delta variant is, noting how the vaccines were not as effective against transmission.
“We’re concerned about the false sense of security that vaccines have ended the pandemic and people who are vaccinated do not need to take any other precautions,” Tedros stated in a report by AFP.
Tedros reminds, “vaccines save lives, but they do not fully prevent transmission.”
Moreover, he cited data that suggests that before the Delta variant arrived, vaccines were found to reduce transmission by about 60 percent. However, with the said variant, that has lessened to about 40 percent.
If an individual is vaccinated, they have a much lower risk of acquiring severe illness and death, but they are still at risk of catching the virus and infecting others, said Tedros.
“We cannot say this clearly enough: even if you are vaccinated, continue to take precautions to prevent becoming infected yourself, and infecting someone else who could die,” the official emphasized.
Taking precautions mean that an individual should continue wearing a facemask, keeping distance, avoiding crowds, and meeting others outside or only in well-ventilated indoor spaces.
According to WHO’s weekly epidemiological report, 99.8 percent of its 845,000 sequences uploaded in the last 60 days to the GISAD global science initiative were Delta variants.
The UN health agency’s technical lead on COVID, Maria Van Kerkhove, stated in the same AFP report that the Delta variant was evolving and the health organization was trying to track changes and circulations in the virus.
She added that the WHO is making plans as they look through future scenarios as to how much the virus will alter in terms of transmissibility, or if there will be a possible future immune escape, which may render some of the existing counter-measures less efficient.
The presently-available COVID-19 vaccines, as WHO has long reiterated, are only essentially aimed at reducing the risks of severe illness, hospitalization, and death, but not completely transmission.
