In Gothenburg, 99-year-old Rosa Johansson received the region's very first vaccination injection.

- She raised her hand when asked who wanted the first dose, says Gabriel Holmqvist, press secretary at the Västra Götaland region.

Rosa Johansson lives in the nursing home Högsbotorp, one of four homes in Gothenburg that was first out when the Västra Götaland region began vaccination on Sunday.

- We chose these four based on the fact that it would be easy with the logistics.

They are located in the same geographical area.

It was a purely practical explanation for the fact that it was the four of them, said Babs Edberg, who coordinates the elderly care's work with covid-19 at a subsequent press conference.

Logistics play a role

Several regions and municipalities state for SVT that precisely practical and logistical reasons weigh heavily when deciding the order of priority.

This includes adjusting the number of doses to the number of people living in the nursing homes.

This is the reasoning in the Gotland region, which received 200 vaccine doses in the first round.

Here, terra nova nursing home was the first out.

- For efficient management, we have tried to select housing where the number of individuals who want to be vaccinated together is just 200. If possible, we want to avoid having "semi-vaccinated" housing, says the region's vaccine coordinator Christine Senter.

In Blekinge and Västnorrland, among others, they reason in the same way and at the same time state that confirmed cases of illness are another factor that determines the order of precedence.

- It is one of the parameters that is taken into account when prioritizing because you must be healthy when you are vaccinated, says Västernorrland's vaccine coordinator Karin Sellgren.

Speed ​​and mode of infection

In the Västerbotten region, which starts its vaccination tomorrow, the Dragon's senior center and Teg's senior center in Umeå are next in line.

The fact that there were two homes in Umeå and not in any other of the region's municipalities is due to the fact that the vaccine delivered to Västerbotten is in a broken cold chain.

This means that you do not have as many days to use the 200 doses that benefit the region and therefore speed became a decisive factor.

In the Norrbotten region, priority has instead been given to the infection situation.

Here, the first vaccine doses have gone to nursing homes in Boden.

- We have a high proportion of those infected in that municipality.

People living in a number of Boden municipality's special housing for the elderly are now offered vaccines, says vaccine coordinator Pia Näsvall.
