疫苗对温度较为敏感,其最适运输温度为0～8℃,在22～25℃左右,所有的疫苗均丧失其效力;含氢氧化铝佐剂的疫苗,在温度低于0℃时也丧失其效力。因此,冷链关系到免疫的成败。 Vaccines are more sensitive to temperature and their optimal transport temperature is 0 to 8 ° C, with all vaccines losing their potency at about 22-25 ° C. Vaccines containing the aluminum hydroxide adjuvant are also lost at temperatures below 0 ° C Its effectiveness. Therefore, the cold chain is related to the success or failure of immunity.
