Travel firm Saga has said that it will only allow people on its cruises and holidays in 2021 if they have received a full coronavirus vaccine.
The travel firm, which caters specifically to over-50s, will require holidaymakers to have been fully vaccinated at least 14 days before they are due to travel.
The new policy will apply to all of the firm's cruises and holidays in 2021, as the brand looks to restart its holidays from May.
Saga only caters to over-50s, so their customers are likely to be in the groups first in line for the vaccine as it is being rolled out.
A Saga spokesperson said: "The health and safety of our customers has always been our number one priority at Saga, so we have taken the decision to require everyone travelling with us to be fully vaccinated against COVID-19.
"Our customers want the reassurance of the vaccine and to know others travelling with them will be vaccinated too. To allow our customers time to get vaccinated, we are moving the restart date for our Travel businesses to May. Our new vaccination policy will be in addition to the detailed arrangements we have already put in place for when cruises and other holidays restart."
The brand has already implemented a series of new health and safety measures across its cruises and getaways following the outbreak of the pandemic.
For cruises specifically, it has unveiled new policies such as requiring passengers to take a pre-departure Covid test in the terminal and undergo medical screening. Onboard measures include a reduced capacity, social distancing measures, enhanced cleaning regimes and expanded medical facilities complete with a dedicated isolation area.
