MP Ian Liddell-Grainger has urged constituents not to delay in getting their coronavirus vaccinations.
He says those called to vaccination centres should make attending them an absolute priority.
Mr Liddell-Grainger, Conservative MP for Bridgwater and West Somerset, said he had been hearing disturbing reports that some elderly people had not been doing so.
“I came across a case of a constituent who had declared they could not attend the centre at the time they had been called because it was too late in the day and it would be dark,” he said.
“We simply cannot allow attitudes like this to slow down a vaccination programme which we have been able to put in place thanks to the outstanding, dedicated work of scientists and with the help of billions of pounds of Government money.
“The time of an appointment may not be completely convenient but that is no reason not to go.”
Covid infections in the constituency are continuing to rise even though ministers now expect the general rate of increase across the country to start to ease as a result of the latest lockdown.
Mr Liddell-Grainger said he accepted the general picture was still bleak some ten months into the pandemic.
“But the huge difference between now and the absolutely powerless situation we were last March is that we now have a vaccine to combat the virus,” he said.
“Scientists have been able to bring us to this stage in record time and it is now up to all of us to make the most effective use of this weapon.
“That means vaccinating the greatest number of people – particularly the elderly and vulnerable – in the shortest possible time.
“But it’s a matter of collective responsibility: we all need to take advantage of vaccination as soon as we are offered it. Anyone delaying is not merely leaving themselves exposed to risk they are automatically risking the lives of others as well.”
