South Korea's health authorities on Saturday issued a new guideline to
vaccination centres across the nation, asking medical staff members to
maximise the number of Covid jabs per vaccine bottle by utilising
innovative syringes.
One day after the start of the nation's
public vaccination program, the Korea Disease Control and Prevention
Agency (KDCA) said a special model of locally produced syringes has
paved the way for increasing the number of vaccine recipients by one to
two per vaccine bottle, Yonhap news agency reported.
The
breakthrough was made possible by the so-called low dead space (LDS)
syringes designed to minimise wasted vaccine doses by reducing space
between the needle and the plunger.
It was previously estimated
that a bottle of AstraZeneca's vaccine was enough to provide jabs to 10
people, while that of Pfizer came to six.
When using the LDS
syringes, however, the KDCA believes a bottle of AstraZeneca's vaccine
can provide jabs for up to 12 people, while that of Pfizer's can
increase up to seven.
"The previous estimate was based on
ordinary types of syringes. Thus, the number of recipients can increase
when we apply the LDS model," said an official from the Central Disease
Control Headquarters.
Authorities, however, said the actual
number of additional recipients can still vary depending on the skills
of each medical staff member.
"Although the new progress can only
add a few thousands jabs for now, the figure is expected to expand
significantly down the road when more Pfizer vaccines are supplied
here," said Chun Eun-mi, Professor at the Ewha Womans University Medical
Centre.
South Korea has secured enough vaccines to inoculate 79
million people, which is much higher than the nation's population of 52
million.
Of the volume, jabs produced by AstraZeneca account for 10 million, while those from Pfizer came to 13 million.
The country aims to achieve herd immunity by November.
