The COVID-19 vaccines don't prevent asymptomatic infection, so those who have been vaccinated can still develop infection and spread it, Head of the Department of Immunology and Molecular Medicine, University of Sri Jayewardenepura, Prof. Neelika Malavige said.

She told the Daily Mirror that the vaccine might prevent asymptomatic infection in some individuals, but not in all.

“Although a person who is vaccinated could still get infected with the virus, his/her viral strain could be less and also the volume of virus in that person’s respiratory secretions is also less, thus the transmission level is less,” Prof. Malavige underscored.

“No vaccine has been proved that they can prevent asymptomatic infection and thus a person, who had got the two doses of vaccine, could still be tested positive with virus through an RT-PCR test. However, here such chances are minimal,” she said.

“This is why masks and social distancing is still considered madatory. Hence, it is essential for the people to strictly abide by the health guidelines such as hand hygiene, wearinh face masks, and social distancing,” she stressed.

However, she said vaccines are very effective in preventing severe disease and death.

"Not only COVID-19 vaccines but some other childhood vaccines don't completely prevent asymptomatic infection but when sufficient numbers are immunised, they reduce transmission and we don't have any problems with them," she added. (Sheain Fernandopulle)

    Day by day Looks as if getting vaccinated won’t make much of a difference and no point calling it’s vaccine

    MM- Very irresponsible and inaccurate to state this! Vaccines should help reduce the severity of symptoms, and reduce deaths. We all need to get vaccinated, but still practice safe measures.

    Mm may be correct no point calling it’s vaccines !!!

    Real-world data from Israel suggests that COVID-19 vaccines will prevent transmission of the coronavirus, in addition to protecting against symptomatic disease. 'usatoday 12th March '21'

    Vaccines are meant to counter the virus, that's the whole idea. Before making statements like this, it should be verified to avoid confusion and fear among people.

    How many know the Covid-19 vaccine death rate worldwide exceeds the Covid-19 death rate (yes, illness prevention is worse than the illness; the vaccine was only shown to reduce illness severity, and that too not categorically so)? How many are aware there now are drug-based treatment protocols with a near perfect record for treatment recovery from Covid-19? How many have heard of the East Virginia Medical School Hospital and its Front Line Covid-19 Critical Care Alliance of physicians who designed a perfectly safe and effective Ivermectin-based treatment protocol that effects a cure, prevents resurgence (2nd infection) and transmission, is approved by the US FDA, and works with near 100% effectiveness as a preventive as well?

    There is yet another100% safe and effective home-based treatment for Covid-19. Simply nebulise a 0.1% solution of food-grade hydrogen peroxide in normal saline water with a drop of iodine 3-5 times a day depending on severity. (Iodine is not essential if your iodine levels are okay). The recovery/cure is 100% within 36-48hrs. This treatment does not require doctors or hospitals. Simple and effective. I know it is, since the protocol worked for a family .member who started it on day 4 of the infection (realising late that she was having Covid-19). She was 80% recovered at the end of day 5, and fully recovered by day 7. Several doctors are using this to treat their patients with 100% results. Vaccine mania has gripped the world, and people are blind to simple, effective antidotes.

    Independent studies done in both the USA and Germany conclusively prove that hydrogen peroxide and providone has no effect on Covid-19.

    She is correct in this instance because it's not yet quite clear at this stage and also kindly note what she said was that "not in all" cases. The Pfizer vaccine reduces severe disease by 92% and hospitalisation by 87%. Even a single dose of Pfizer or Astra-Zenaca cuts hospitalisation by 80%. There's large data available from Israel
